Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, specifically to a baling machine anti-blocking structure. Background Technology

[0002] Metal scrap balers are industrial equipment specifically designed for compressing and processing metal scrap. Their core function is to compress loose metal scrap into regular blocks under high pressure, making them easy to store, transport, and recycle. They are widely used in metal recycling and processing, smelting industries, and end-of-life vehicle processing.

[0003] If too much material is added during the feeding process of existing baling machines, it can easily cause blockage in the high-pressure zone, leading to the equipment malfunctioning. Once blocked, the compressed material is often difficult to clean, requiring manual chiseling to clear it bit by bit, which is time-consuming, labor-intensive, and increases labor costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a reverse-push anti-blocking structure for a baling machine. When blockage occurs, there is no need for manual chiseling to clear the waste material; simply pressing a button automatically ejects the blocked material. This solves the technical problem of material blockage and the difficulty in cleaning compressed material.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reverse-push anti-blockage structure for a baling machine, comprising a reverse-push cylinder, a reverse-push push head, a pressure sensor, and a control system. The reverse-push cylinder is fixed to the front wall plate of the baling machine by bolts. The reverse-push push head is embedded inside the front wall plate of the high-pressure chamber of the baling machine. The reverse-push push head is connected to the reverse-push cylinder. The pressure sensor is installed inside the high-pressure chamber of the baling machine to detect the material pressure. The control system is electrically connected to the pressure sensor and the reverse-push cylinder. When the pressure sensor detects that the pressure inside the high-pressure chamber exceeds a preset threshold, the control system automatically starts the reverse-push cylinder, driving the reverse-push push head forward to push the blocked material out of the high-pressure chamber of the baling machine.

[0008] Furthermore, the piston rod end of the reverse thrust cylinder is provided with a quick connector, and the corresponding position of the reverse thrust head is provided with a matching connecting groove, so that the quick connector and the connecting groove can be quickly disassembled and assembled.

[0009] Furthermore, the working surface of the reverse push head is an arc-shaped curved surface, and its radius of curvature matches the inner wall of the high-pressure chamber of the baler.

[0010] Furthermore, it also includes a limit switch, which is set at the end of the stroke of the reverse thrust cylinder to limit the maximum stroke of the reverse thrust head.

[0011] Furthermore, the surface of the reverse thrust head is provided with a wear-resistant coating, the thickness of which is 2-5mm.

[0012] Furthermore, the thrust cylinder is a double-acting hydraulic cylinder with a working pressure of 10-20 MPa.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a reverse-pushing anti-blockage structure for a baling machine, which has the following beneficial effects:

[0015] This baler's anti-blockage structure is easy to use, requiring no complicated installation or debugging. When blockage occurs, there's no need for manual chiseling to remove the material; simply pressing a button automatically ejects the blocked material, significantly saving labor costs. This improves the baler's operating efficiency and stability, reducing downtime caused by blockages. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1A reverse-push anti-blocking structure for a baler includes a reverse-push cylinder 1, a reverse-push head 2, a pressure sensor 3, and a control system 4. The reverse-push cylinder 1 is bolted to the front wall plate of the baler 5. The reverse-push head 2 is embedded inside the front wall plate of the high-pressure chamber of the baler 5 and is connected to the reverse-push cylinder 1. The pressure sensor 3 is installed inside the high-pressure chamber of the baler 5 to detect material pressure. The control system 4 is electrically connected to the pressure sensor 3 and the reverse-push cylinder 1. When the pressure sensor 3 detects that the pressure inside the high-pressure chamber exceeds a preset threshold, the control system 4 automatically starts the reverse-push cylinder 1, driving the reverse-push head 2 forward to push the blocked material 9 out of the high-pressure chamber of the baler 5. The reverse-push anti-blocking structure also includes a limit switch 8, which is installed at the end of the stroke of the reverse-push cylinder 1 to limit the maximum stroke of the reverse-push head 2.

[0020] In the above-mentioned embodiment, the reverse thrust cylinder 1 is a double-acting hydraulic cylinder with a working pressure of 10-20MPa. The piston rod end of the reverse thrust cylinder 1 is provided with a quick connector 6, and the corresponding position of the reverse thrust push head 2 is provided with a matching connecting groove 7. The quick connector 6 and the connecting groove 7 can be quickly disassembled and assembled. The working surface of the reverse thrust push head 2 is an arc-shaped curved surface, and its radius of curvature matches the inner wall of the high-pressure chamber of the baler 5. The surface of the reverse thrust push head 2 is provided with a wear-resistant coating with a thickness of 2-5mm.

[0021] The working principle of the above embodiments is as follows:

[0022] During normal feeding of the baler 5, to prevent overfeeding from causing blockage in the high-pressure zone, the control system 4 automatically activates the reverse thrust cylinder 1 when the pressure sensor 3 detects that the pressure inside the high-pressure chamber exceeds a preset threshold. The reverse thrust cylinder 1 precisely controls its forward movement, using its thrust to drive the reverse thrust head 2 forward along a preset track until the blocked material 9 is completely pushed out of the high-pressure chamber of the baler 5. In addition to the automatic control module controlled by the pressure sensor 3, the control system 4 also includes a manual control module, allowing operators to switch to manual mode for the aforementioned anti-blockage reverse thrust operation.
